RAPID: A Numerical Investigation of Relativistic Jets from Spinning Black Holes and Neutron Stars

相对论性喷流通常出现在吸积黑洞系统中。然而，最近在一些中子星系统中也发现了喷流，这意味着相对论性喷流只需要一个致密的相对论性恒星，而不一定是黑洞。本项目使用广义相对论磁流体力学代码对黑洞和中子星的相对论喷流进行数值模拟，以识别这两种系统的异同。最近，Narayan教授的研究生对这个问题进行了初步研究，得出了非常有趣的结果，在短时间内，他有机会继续研究这个问题，然后再去别处做他的论文。由最熟悉的人所做的研究具有明显的内在价值，并且他的论文研究的扩展将为这位初级研究员提供在进入下一阶段职业生涯之前扩展到新领域的机会。该奖项是根据快速反应研究（Rapid）计划授予的。

Relativistic jets are generally found to occur in accreting black hole systems. Recently, however, jets have also been seen in a few neutron star systems, implying that a relativistic jet needs only a compact relativistic star, and not necessarily a black hole. This project consists of numerical simulations of relativistic jets from black holes and neutron stars using a general relativistic magnetohydrodynamics code, in order to identify similarities and differences in the two kinds of system. Very recent preliminary work on this problem by Professor Narayan's finishing graduate student has led to very interesting results, and an opportunity has arisen at short notice to keep that student working on this problem before taking up his post-thesis appointment elsewhere. There is clear intrinsic value to the research being done by the person most familiar with it, and this extension of his thesis research will provide this junior researcher with an opportunity to expand into a new area before moving on to the next stage of his career.This award is made under the Grants for Rapid Response Research (RAPID) program.
